  • Finally finished checking a new SanDisk Ultra micro SD card with Use h2testw ( https://h2testw.en.lo4d.com/windows ). Has a claimed "Up to 100 MB/s transfer read speed".

    Results:

    Warning: Only 121909 of 121910 MByte tested.
    Test finished without errors.
    You can now delete the test files *.h2w or verify them again.
    Writing speed: 8.31 MByte/s
    Reading speed: 2.10 MByte/s
    H2testw v1.4

    Before I get grumpy and return it, is there anything I could be doing wrong? I'm using the supplied adapter in my laptop's SD slot. The adapter was thrown in the bag loose rather than being in the SanDisk packet.
